FreeBSD 12.0 Release Process

Introduction

This is the release schedule for FreeBSD12.0. For more information about the release engineering process, please see the Release Engineering section of the web site.

General discussions about the pending release and known issues should be sent to the public freebsd-current mailing list. MFC requests are no longer being accepted for releng/12.0.

Schedule

During the head freeze, the Release Engineering Team may create ALPHA snapshots to publish for testing purposes. As the frequency and total number of the ALPHA snapshots will depend on the length of time the head branch is frozen, no official schedule is provided.

Announcements regarding the availability of the ALPHA snapshots will be sent to the freebsd-current and freebsd-snapshots mailing lists.
